SByte.MaxValue Field

public: System::SByte MaxValue = 127;

public const sbyte MaxValue = 127;

val mutable MaxValue : sbyte

Public Const MaxValue As SByte  = 127

The following example uses the MinValue and MaxValue fields to verify that an Int64 value is within the range of the SByte type before it performs a type conversion. This verification prevents an OverflowException at run time.

long longValue = -130;
sbyte byteValue; 

if (longValue <= sbyte.MaxValue && 
    longValue >= sbyte.MinValue)
{    
   byteValue = (sbyte) longValue;
   Console.WriteLine("Converted long integer value to {0}.", byteValue);
}   
else
{
   sbyte rangeLimit;
   string relationship;
   
   if (longValue > sbyte.MaxValue)
   {
      rangeLimit = sbyte.MaxValue;
      relationship = "greater";
   }   
   else
   {
      rangeLimit = sbyte.MinValue;
      relationship = "less";
   }       

   Console.WriteLine("Conversion failure: {0:n0} is {1} than {2}.",  
                     longValue, 
                     relationship, 
                     rangeLimit);
}

let longValue = -130L

if longValue <= int64 SByte.MaxValue && longValue >= int64 SByte.MinValue then
    let byteValue = int8 longValue
    printfn $"Converted long integer value to {byteValue}."
else
    let rangeLimit, relationship =
        if longValue > int64 SByte.MaxValue then
            SByte.MaxValue, "greater"
        else
            SByte.MinValue, "less"

    printfn $"Conversion failure: {longValue:n0} is {relationship} than {rangeLimit}."

Dim longValue As Long = -130
Dim byteValue As SByte 

If longValue <= SByte.MaxValue AndAlso _
   longValue >= SByte.MinValue Then
   byteValue = CSByte(longValue)
   Console.WriteLine("Converted long integer value to {0}.", byteValue)
Else
   Dim rangeLimit As SByte
   Dim relationship As String
   
   If longValue > SByte.MaxValue Then

The value of this constant is 127; that is, hexadecimal 0x7F.
